【摘要】：本论文从提高齿科用复合树脂基体的性能入手,侧重于新型树脂基体的设计合成及性能研究,通过设计并合成两种新型高性能低粘度的复合树脂基体,并对其结构、性能和毒性进行了详细研究。1.利用羟醛缩合反应,合成四甲基双酚F化合物,并将该产物与环氧氯丙烷反应,得到四甲基双酚F型环氧树脂。继而将该环氧树脂与丙烯酸反应,合成新型复合树脂单体—四甲基双酚F型丙烯酸酯,研究其结构和性能的关系,对其生物毒性进行评价。并与Bis-GMA按不同比例混合,筛选最佳配比复合树脂体系。2.设计并合成了一种含三氟甲基的新型聚合物——间三氟甲基苯基型丙烯酸酯,研究其结构和性能的关系,对其生物毒性进行评价。并与Bis-GMA按不同比例混合,筛选最佳配比复合树脂体系。3.分析了不同浓度的TEGDMA对两种新型复合树脂基质性能和毒性的影响,筛选出最佳配方。新型复合树脂基质有望成为替代Bis-GMA的备选基质。
[Abstract]:In this paper, we focus on the design, synthesis and study of the new resin matrix. Through the design and synthesis of two new high performance and low viscosity composite resin matrix, and the structure of the composite resin matrix, the paper begins with the improvement of the performance of the composite resin matrix used in dentistry, focusing on the design, synthesis and properties of the new resin matrix. The performance and toxicity were studied in detail. Tetramethyl bisphenol F compound was synthesized by the condensation of hydroxyl aldehyde and reacted with epichlorohydrin to obtain tetramethyl bisphenol F type epoxy resin. A new composite resin monomer, tetramethyl bisphenol F type acrylate, was synthesized by the reaction of the epoxy resin with acrylic acid. The relationship between the structure and properties of the resin was studied and its biological toxicity was evaluated. The optimum compound resin system. 2. 2 was mixed with Bis-GMA in different proportion. A novel polymer containing trifluoromethyl-m-trifluoromethyl phenyl acrylate was designed and synthesized. The relationship between its structure and properties was studied and its biological toxicity was evaluated. The optimum compound resin system. 3. 3 was mixed with Bis-GMA in different proportion. The effects of different concentrations of TEGDMA on the properties and toxicity of two new composite resins were analyzed. The new composite resin matrix is expected to be a substitute for Bis-GMA.
